Description

Technical Field

[0001] This utility model relates to the field of smart lock technology, specifically to an installation structure for the front panel of a smart lock. Background Technology

[0002] In the field of smart locks, external smart locks are widely used due to their convenient installation and strong adaptability. These smart locks typically consist of a rear panel with a motor assembly installed inside the door, a front panel installed outside the door, and a mechanical lock cylinder installed between the front and rear panels. Among these, the mechanical lock cylinder, as the core transmission component, directly affects the lock's performance due to the precision of its installation with the front and rear panels.

[0003] The typical installation process for existing external smart locks is as follows: First, the rear base plate is fixed to the inside of the door panel. Then, the mechanical lock cylinder is installed, with its tail rod passing through the through hole in the rear base plate. Next, the front panel is connected to the mechanical lock cylinder, and finally, the rear panel with the motor assembly is fixed. This installation method relies on the initial positioning accuracy of the rear base plate. However, in actual operation, due to factors such as door panel size errors and operator deviations, the rear base plate may experience lateral positional shifts, meaning it may deviate along the width of the door panel. Because the connection structure between the mechanical lock cylinder and the front panel in existing technology lacks lateral position adjustment functionality, if the rear base plate is installed incorrectly, its position cannot be changed since it is pre-installed and fixed. This means that the mechanical lock cylinder's position relative to the front panel can only be adjusted passively by adjusting the front panel. This often results in the front panel being forced close to or far from the side edge of the door panel after installation, affecting the normal use of the smart lock.

[0004] On the one hand, the gap between the front panel and the door frame is too small, which can easily cause interference when closing the door, preventing the door panel from opening and closing properly, and even causing malfunctions such as jammed lock tongue and motor overload. On the other hand, if forced to install, it may cause wear and tear on the edges of the door panel, or damage to internal parts due to uneven force on the mechanical lock cylinder, significantly reducing the service life of the smart lock. More problematic is that if there is an installation deviation in the existing technology, the front panel, mechanical lock cylinder, rear base plate, and other components must be completely disassembled, the position of the rear base plate must be readjusted, and holes must be drilled again for fixation. This is not only time-consuming and labor-intensive, but can also cause irreversible damage to the door panel, such as enlarging the mounting holes, adding screw holes, etc., which greatly increases the installation cost and maintenance difficulty.

[0005] Therefore, overcoming the aforementioned shortcomings has become an important issue that urgently needs to be addressed by those skilled in the art. Utility Model Content

[0014] Furthermore, the first through hole includes a circular central hole for the tail rod to rotate, wiring holes symmetrically arranged on both sides of the circular central hole, and arc-shaped positioning elongated holes symmetrically arranged on both sides of the wiring holes. The positioning elongated holes include positioning ends symmetrically arranged vertically, and a first positioning pin capable of being inserted into the positioning end is provided on the rear side of the first connecting seat.

[0015] Furthermore, the lock cylinder is cylindrical, and the first connecting seat includes symmetrically arranged upper and lower limiting arc-shaped concave surfaces.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] To address the difficulties in adjustment and poor reliability caused by rear base plate position deviations during the installation of existing external smart locks, this invention proposes a front panel mounting structure for smart locks with a position adjustment mechanism. By incorporating a position adjustment mechanism between the rear base plate and the front panel to adjust the lateral position of the mechanical lock cylinder relative to the front panel, flexible adjustment of the mechanical lock cylinder's lateral position relative to the front panel is achieved. This compensates for installation errors of the rear base plate, ensures a reasonable distance between the front panel and the side edge of the door panel, effectively prevents damage to components involved in door gaps, and fundamentally improves the convenience and reliability of smart lock installation. This invention, through the position adjustment mechanism between the mechanical lock cylinder and the front panel, allows for flexible adjustment of the lateral position of the front panel without disassembling the rear base plate and the mechanical lock cylinder, effectively compensating for installation errors and preventing failure of components involved in door gaps. This design, while maintaining a simple structure, significantly improves the ease of installation, reliability, and maintenance economy of smart locks. Attached Figure Description

[0027] The following examples provide a more detailed description of the features and other related characteristics of this utility model, to facilitate understanding by those skilled in the art:

[0028] For ease of description and understanding, please refer to the orientation shown in the accompanying drawings of the instruction manual for descriptions related to positional relationships such as front, back, top, bottom, left, right, outside, and inside, as well as descriptions related to directions such as horizontal and vertical.

[0029] like Figures 1 to 7As shown, this case discloses an installation structure for a smart lock front panel, including a rear base plate 1, a front panel 2, and a mechanical lock cylinder 3 installed between the rear base plate 1 and the front panel 2. The front panel 2 provides front-end support for the mechanical lock cylinder 3, ensuring that the lock cylinder part 31 is coaxially installed with the front panel 2. It is also used for installation on the outside of the door to provide users with smart lock functional interactions, such as fingerprint unlocking and key mechanical unlocking. The mechanical lock cylinder 3 includes a lock cylinder part 31 and a tail rod 32 connected to the rear side of the lock cylinder part 31. The lock cylinder part 31 has a keyhole 311. The tail rod 32 is usually called a lock bar, tail lever, or transmission rod in the lock cylinder field. It is usually a long square rod. Its core function is to transmit the rotational movement of the lock cylinder to the bolt or other locking mechanisms, or in the field of smart locks, to drive in reverse by a motor to drive the reverse tail rod to rotate, thereby driving the lock cylinder to rotate and realize the unlocking or locking operation. A mounting hole 21 is provided on the rear side of the front panel 2. The front end of the lock cylinder part 31 of the mechanical lock cylinder 3 is fixed in the mounting hole 21 by a fixing piece 9, and the rear end is fixed to the rear base plate 1 by a first connecting seat 4. By setting the fixing piece 9, the lock cylinder part 31 is firmly connected to the mounting hole, ensuring the stability of the connection between the lock cylinder part 31 and the front panel 2. The mounting hole 21 provides a connection position for the lock cylinder part 31 of the mechanical lock cylinder 3 to the front panel 2, and the lock cylinder part 31 is installed in the mounting hole 21. The first connecting seat 4 is used to connect and fix the mechanical lock cylinder 3 to the rear base plate 1, making the mechanical lock cylinder 3 more stable. The first connecting seat 4 disperses the force on the mechanical lock cylinder during operation, avoiding stress concentration caused by single-point fixing, and effectively ensuring the stability of the mechanical lock cylinder 3 when rotating to lock and unlock. A first through hole 11 is provided on the rear base plate 1, and the tail rod 32 extends backward through the first through hole 11 and can rotate in the first through hole 11. In specific implementation, the lock cylinder 31 is connected to the front panel 2, and the tail rod 32 is used to pass through the rear base plate 1 and connect to the rear panel with a motor assembly inside the door, as mentioned in the background art. The tail rod 32 is then driven by the motor assembly of the rear panel, thereby achieving electronic unlocking. A position adjustment mechanism is also provided between the rear base plate 1 and the front panel 2 to adjust the lateral installation position of the mechanical lock cylinder 3 relative to the front panel 2. The lateral installation position of the mechanical lock cylinder 3 relative to the front panel 2 is as follows... Figure 3The direction is shown. Since the rear base plate 1 and mechanical lock cylinder 3 are pre-installed and fixed, the front panel can still be adjusted through the position adjustment mechanism, thereby adjusting the distance between the front panel 2 and the side of the door panel. This effectively prevents the front panel from being too close to the door panel, causing door gap interference, inability to open and close the door, etc. By setting up a position adjustment mechanism, this case allows for direct adjustment of the lateral position of the front panel 1 without disassembling the rear base plate 1 and mechanical lock cylinder 3, avoiding the overall rework caused by errors in traditional installation. It enables flexible adjustment of the distance between the front panel 1 and the side of the door panel, effectively preventing interference when closing the door, ensuring normal opening and closing of the door panel and long-term stable operation of the lock components. There is no need to re-drill holes in the door panel or replace parts, significantly reducing installation and maintenance time and costs, and significantly improving the installation convenience, reliability, and maintenance economy of the smart lock.

[0030] Specifically, refer to Figures 1-3 , Figure 7 As shown, the position adjustment mechanism of this case includes a second connecting seat 5 installed on the front panel 2 and exposed through the mounting hole 21. The second connecting seat 5 has a first connecting hole 51 for installing the lock cylinder part 31. At least two first connecting holes 51 are arranged horizontally side by side, and the lock cylinder part 31 is installed in one of the first connecting holes 51.

[0031] In specific implementation, the second connecting seat is integrally formed with the front panel 2 to enhance its connection strength. The rear base plate 1, the first connecting seat 4, the mechanical lock cylinder 3, and the front panel 2 are connected and fixed together by fasteners 6. In a preferred embodiment, three first connecting holes 51 are preferably provided to achieve a greater degree of lateral adjustment. That is, by installing the lock cylinder in the first connecting holes 51 at different positions, the lateral position of the mechanical lock cylinder 3 relative to the front panel 2 can be adjusted by switching the hole positions. Of course, the user can also choose to set more or fewer first connecting holes 51, and the spacing between the first connecting holes 51, to achieve multi-level adjustment of the lateral position of the mechanical lock cylinder 3 relative to the front panel 2. The design of the multi-position hole adjustment mechanism further facilitates the adjustment of the installation position of the smart lock front panel 1. Utilizing the second connecting seat 5 integrally formed with the front panel and the horizontally arranged first connecting holes 51, the position of the mechanical lock cylinder 3 can be quickly switched, thereby flexibly adjusting the distance between the front panel 2 and the side of the door panel. This solution, while maintaining a simple and reliable structure, effectively addresses the pain point of difficult-to-correct installation errors in existing technologies, providing a standardized and efficient adjustment solution for the engineering installation of smart locks.

[0032] like Figures 1-4As shown, a fastening mechanism is further provided between the rear base plate 1 and the second connecting seat 5 to ensure a stable connection between them. Specifically, the fastening mechanism includes second connecting holes 52 that symmetrically begin at the upper and lower ends of the first connecting hole 51, and fasteners 6 that pass sequentially from back to front through the rear base plate 1 and the first connecting seat 4 and finally connect to the second connecting hole 52. A second through hole 12 is provided on the rear base plate 1 for the fasteners 6 to pass through. In this embodiment, the rear base plate 1, the first connecting seat 4, the mechanical lock cylinder 3, and the second connecting seat 5 of the front panel 2 are connected and fixed to each other by a fastening mechanism. The rigid connection of the four components eliminates relative displacement, which greatly reduces the mechanical failure rate, especially in frequent unlocking / locking operations. In this embodiment, the fasteners 6 can be bolts, screws, or other connecting fasteners. In practical implementation, a chamfer or countersunk head is provided at the opening of the second through hole 12 to ensure that the head of the fastener 6 is flush with or slightly lower than the surface of the rear base plate 1. By setting the fastener 6, while maintaining the position adjustment function, the rigid integrated connection effectively resists the torque when the mechanical lock cylinder 3 rotates, significantly improving the anti-loosening performance.

[0033] Continue to refer to Figures 1-4 As shown in the preferred embodiment of this invention, the fastener 6 includes a threaded tube 61 with internal threads and a screw 62 threadedly connected to the threaded tube 61. The threaded tube 61 has an internally hollow structure to allow the screw 62 to be inserted. The threaded tube 61 includes a first connecting end 611 for connecting to the screw 62 and a second connecting end 612 for connecting to a second connecting hole 52. The diameter of the first connecting end 611 is larger than the diameter of the second connecting end 612. The second connecting end 612 has external threads 6121 and internal threads in the second connecting hole 52, and the second connecting end 612 is threadedly connected to the second connecting hole 52. This invention provides a stepped threaded tube and a double-threaded adjustment scheme by setting an adjustable fastener 6, which realizes the adaptation of the smart lock installation across the door panel thickness, and the threaded connection method makes adjustment and installation convenient. Users can adjust the overall length of the fastener by adjusting the threaded connection between the screw tube 61 and the screw rod 62. In other words, the design of the screw tube 61 and the screw rod 62 allows for adjustable length of the fastener 6, facilitating adjustment of the distance between the rear base plate 1 and the front panel 2, thus enabling installation on door panels of different thicknesses. That is to say, in addition to the fasteners in this embodiment, the fastener 6 can be a single screw or a riveted component, or other connection methods, to fix the rear base plate 1, the first connecting seat 4, the mechanical lock cylinder 3, and the front panel 1.

[0034] In practice, the distance between the rear base plate 1 and the second connecting seat 5 is estimated by measuring the thickness of the door panel to be installed. The relative position of the screw tube 61 and the screw 62 is adjusted by rotating the screw rod 62 so that the overall length of the fastener is slightly greater than the estimated distance. The second connecting end 612 of the screw tube 61 is screwed into the second connecting hole 52 of the second connecting seat 5 until it fits tightly. The screw rod 62 is inserted through the second through hole 12 of the rear base plate 1 and the first connecting end 611 of the screw tube 61 is screwed in. The screw rod 62 is rotated using a tool, which simultaneously drives the screw tube 61 to rotate and tighten the rear base plate 1 and the second connecting seat 5.

[0035] Reference Figures 1-5 As shown, a positioning groove 41 is provided on the first connecting seat 4 for the fastener 6 to pass through, and the fastener 6 fits tightly in the positioning groove 41. That is to say, the positioning groove 41 plays a positioning and guiding role, which facilitates the quick installation of the first connecting seat 4, the mechanical lock cylinder 3, the rear base plate 1 and the fastener 6. At the same time, the symmetrical arrangement of the fasteners 6 in conjunction with the positioning groove 41 improves the stability of the first connecting seat 4 and the mechanical lock cylinder 3, counteracts the overturning moment generated when the mechanical lock cylinder 6 rotates, and maintains the stability of the first connecting seat 4. In a specific implementation, the fixing piece 9 includes a fourth through hole 91 for the lock cylinder 31 to pass through and a fifth through hole 92 for the fastener 6 to pass through. The lock cylinder 31 passes through and is installed in the fourth through hole 91. The lock cylinder 31 is cylindrical, and the shape of the fourth through hole 91 is circular to match the lock cylinder 31 for positioning. The front end of the lock cylinder 31 is installed in the first connecting hole 51. The fifth through hole 92 is for the fastener 8 to pass through. The fastener 6 is fastened to the second connecting hole 52, thereby fixing the fixing piece 9 to the second connecting seat 5. The upper and lower fasteners 8 pass through the fifth through hole 92 on the fixing piece 9 to securely install the lock cylinder 31 on the second connecting seat 5, pressing and fixing the lock cylinder 31 to prevent vertical displacement and loosening. A limiting protrusion 312 is provided on the lock cylinder 31. The fixing piece 9 includes a limiting groove 93 opened on the side of the fourth through hole 91 for the limiting protrusion 312 to be inserted and limited. Based on the previous embodiment, the locking cylinder 31 is locked in all directions by the limiting cooperation of the limiting protrusion 312 and the limiting groove 93, which can effectively prevent it from moving laterally, longitudinally and circumferentially, ensure the stability of the connection between the locking cylinder 31 and the second connecting seat 5, and prevent the mechanical lock cylinder 3 from moving or loosening due to external force or rotation, thus effectively ensuring the stability of the operation of the mechanical lock cylinder 3.

[0036] Furthermore, such as Figures 1-6As shown, to further ensure the stability of the connection between the first connecting seat 4 and the rear base plate 1, a first screw hole 42 is provided on the rear side of the first connecting seat 4, and a third through hole 13 is provided on the rear base plate 1. A first screw 7 is installed in the third through hole 13, and the front end of the first screw 7 passes through the third through hole 13 and is threaded into the first screw hole 42. In this case, the first connecting seat 4 is firmly connected and fixed to the rear base plate 1 by means of threaded connection. Through the synergistic effect of circumferential constraint and axial fastening, the mechanical lock cylinder 3 is prevented from generating a circumferential rotational force on the first connecting seat 4 when rotating, which would cause the first connecting seat 4 to loosen.

[0037] Continue to refer to Figures 1-6 As shown, the first through hole 11 includes a circular central hole 111 for the tail rod 32 to rotate, wiring holes 112 symmetrically arranged on both sides of the circular central hole 111, and arc-shaped positioning elongated holes 113 symmetrically arranged on both sides of the wiring holes 112. In a specific implementation, the wiring holes 112 are used for the wires of the front panel 2 to pass through and make electrical connections with the electronic components in the rear panel with the motor.

[0038] The positioning hole 113 includes symmetrically arranged positioning ends 1131, and a first positioning pin 43 is provided on the rear side of the first connecting seat 4 to be inserted into the positioning ends 1131. That is, four first positioning pins 43 are provided, corresponding one-to-one with the positioning ends 1131, and are inserted into the corresponding positions of the positioning ends 1131. In this invention, the cooperation between the first positioning pins 43 and the positioning ends 1131 facilitates quick guiding and positioning installation between the first connecting seat 4 and the rear base plate 1; at the same time, it can effectively limit the displacement of the first connecting seat 4; and it can also effectively prevent the first connecting seat 4 from loosening due to the circumferential rotational force generated on the first connecting seat 4 when the mechanical lock cylinder 3 rotates.

[0039] In specific implementation, such as Figures 1-5 As shown, the lock cylinder 31 is cylindrical, and the first connecting seat 4 includes symmetrically arranged upper and lower limiting arc-shaped concave surfaces 44. The lock cylinder 31 is limited between the upper and lower limiting arc-shaped concave surfaces 44. The first connecting seat 4 has a sixth through hole 45 for the tail rod 32 to pass through. Through the cooperation of the upper and lower limiting arc-shaped concave surfaces 44 and the cylindrical lock cylinder 31, the lock cylinder 31 can be well limited and fixed, thereby ensuring the stability of the mechanical lock cylinder 3 connection; at the same time, it can play a circumferential limiting role, preventing the first connecting seat 4 from loosening due to the circumferential rotational force generated on the first connecting seat 4 when the mechanical lock cylinder 3 rotates.

[0040] like Figure 1 , Figure 2 , Figure 6 As shown, a second screw hole 14 is provided on the rear bottom plate 1, and a second screw 8 for connecting with the door panel is installed in the second screw hole 14 to facilitate the secure installation of the rear bottom plate 1 onto the door panel.

[0041] Furthermore, such as Figure 1 , Figure 7 As shown, a numeric keypad panel 22, a card swipe panel 23, a fingerprint recognition head 24, and a mechanical unlocking panel 25 are provided on the front side of the front panel 2 to realize the functions of password unlocking, card unlocking, fingerprint unlocking, and key unlocking of the smart lock, so as to meet the different usage habits of users, cover the unlocking needs of all scenarios, and make it especially convenient for specific users such as the elderly and children.

[0042] The lock cylinder 31 passes through the mounting hole 21, exposing the keyhole 311 on the mechanical unlocking panel 25 for easy unlocking with a key. A cover plate 26 is hinged to the mechanical unlocking panel 25 to cover the keyhole 311. A second positioning pin 261 is provided on the inner side of the cover plate 26, and a positioning hole 251 is provided on the mechanical unlocking panel 25 for the second positioning pin 261 to be inserted. The cover plate 26 is used to cover and conceal the keyhole 311, improving security and preventing foreign objects from blocking it or rainwater from entering and causing damage. The cooperation between the second positioning pin 261 and the positioning hole 251 facilitates the closing of the cover plate 26 and also makes it easy to lock the cover plate 26 to prevent it from shaking or being accidentally opened. In a specific implementation, the closing method between the cover plate 26 and the mechanical unlocking panel 25 can also be a magnetic attraction method. A USB interface 252 is installed on the mechanical unlocking panel 25. In practice, the USB interface 252 is preferably the widely used Type-C interface for better compatibility. Since the power box of the smart lock is installed on the rear panel inside the door, the door cannot be opened when the smart lock's power is off. By setting up the USB interface 252, an external power source can be connected to the USB interface 252 to power the smart lock when the mains are down, thus enabling temporary opening. After the user opens the door, they can replace the power source themselves from the rear panel inside the door. The functional components of the front panel 1 in this design are integrated through a multi-dimensional design, combining a convenient human-machine interface with a reliable security structure. From multi-modal unlocking methods to the concealed protection of the mechanical key, and the setting of the emergency power supply interface, each technical feature revolves around the core requirements of "safety, convenience, and reliability," effectively meeting the diverse needs of users.

[0043] As stated above, this case protects the installation structure of a smart lock front panel, and all technical solutions that are the same as or similar to this case should be considered to fall within the protection scope of this case.
